Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.05106 |
| Opus 5.5 | $0.00008 | $0.02042 |
| Sonnet 5.5 | $0.00004 | $0.01021 |
| Haiku 4.5 | $0.00002 | $0.00511 |
Grade A, and why
spec-add scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Spec Add Command
Overview
Unified command for adding specs one at a time. Supports both interactive wizard mode and direct CLI mode.
Key Features:
- Supports both project specs and personal specs
- Scope selection (global vs project) for personal specs
- Category-based organization for workflow stages
- Interactive wizard mode with smart defaults
- Direct CLI mode with auto-detection of type and category
- Auto-confirm mode (
-y/--yes) for scripted usage
Use Cases
- During Session: Capture important decisions as they're made
- After Session: Reflect on lessons learned before archiving
- Proactive: Add team conventions or architectural rules
- Interactive: Guided wizard for adding rules with full control over dimension, scope, and category
Usage
$spec-add # Interactive wizard (all prompts)
$spec-add --interactive # Explicit interactive wizard
$spec-add "Use async/await instead of callbacks" # Direct mode (auto-detect type)
$spec-add -y "No direct DB access" --type constraint # Auto-confirm, skip confirmation
$spec-add --scope global --dimension personal # Create global personal spec (interactive)
$spec-add --dimension specs --category exploration # Project spec in exploration category (interactive)
$spec-add "Cache invalidation requires event sourcing" --type learning --category architecture

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

spec-add is a skill published in the GitHub repository catlog22/Claude-Code-Workflow (2,124 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 5,106 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
